Description

Sampling event logs from cruises WS1010 and AT18-02 in the Gulf of Mexico during 2010.

Methods & Sampling

Dataset acquisition description

AT18-02 Notes:
11/27/10 Operations: Brine Microbial Observatory Project (included in another data submission).
11/30/10: Subsequent MUC/CTD operations were not completed due to the bad weather.

WS1010 Notes:
There were no stations numbered 65 and 74.
There was no CTD cast number 78.
Personnel transfers took place on 5/29/10 and 6/2/10 to 6/3/10.

Data Processing Description

Dataset Processing Description

BCO-DMO made the following modifications to the original event logs:
For both cruises:
- Changed parameter names to conform with BCO-DMO convention.
- Replaced blanks with 'nd' to indicate 'no data'.

AT18-02:
- Dates and time were assumed to be local (based on dates/times in the CTD data).
- Added the 'comment' column for misc. sampling notes.
- Separated the original 'event_description' column into 'instr', 'cast', and 'action'.
- Added event numbers ending in 'b' for instrument recovery events.
- Added event numbers for transit events.
- Added the following events: 11.07, 12.07, 15.03 (these events were recorded in the original event log, but did not have distinct event numbers).
-Corrected event number of event 12.08 (was originally recorded as 12.06, creating a duplicate event number).
-For events 15.01b, 15.02, and 15.02b, changed date from 12/1 to 12/2, based on time passing midnight.

WS1010:
-Dates and times were assumed to be UTC (based on dates/times in the CTD data).
